The present invention relates to a method for synthesizing a frequency image, which comprises the steps of: estimating a center frequency for each band of a received signal; separating the received signal into each band using the estimated center frequency of each band; estimating the energy of each band using a result obtained from separating the received signal into each band; determining a weighting factor for each band from the estimated energy; and synthesizing a frequency image for each band by applying the determined weighting factor for each band to the result obtained from separating the received signal into each band, in order to provide an improved ultrasonic image having high contrast. |
